Experimental campaign to test the capability of STARDUST-upgrade diagnostics to investigate LOVA and LOCA conditions

Given the urgent need to converge on precise guidelines for accident management in nuclear fusion plants, an experimental campaign has been carried out on the "STARDUST-Upgrade" facility for dust mobilization phenomena investigation at the University of Rome "Tor Vergata", in the framework of the activities of the Quantum Electronics and Plasma Physics (QEP) Research Group. The main purpose of this preliminary work is to test the "STARDUST-Upgrade" capability to investigate not only Loss of Vacuum Accident (LOVA) but also Loss of Coolant Accident (LOCA) accidents and their consequences. In fact, an upper port of "STARDUST-Upgrade" is used as an inlet port, reproducing coolant loss consequences from the upper ports of the vacuum vessel in ITER. The diagnostics required for these experimental studies and the results of this first experimental campaign are presented.
